Your "Student is not a container you have to fill, but a torch you have to light up." Albert Einstein
I love this quote by Albert Einstein. He sums up how I have tried to inspire all homeschoolers with my science manuals. I try to ask questions to spark the student's interest, to get a fire of inspiration and an excitement for biology, or any aspect of the physical sciences. Science is FUN! There is so much to explore, to find out answers to the whys of our world around us. When your student discovers the why, he understands and does not have to memorize. When your student discovers the why, the torch gets sparked and its flame begins to grow.
You, as the parent/teacher can spark your student's torch! Hang in there, the hard work of homeschooling will show its rewards in the years to come.
